      futex: Remove duplicated code and fix undefined behaviour · 30d6e0a4
      由 Jiri Slaby 提交于 
      There is code duplicated over all architecture's headers for
futex_atomic_op_inuser. Namely op decoding, access_ok check for uaddr,
and comparison of the result.

Remove this duplication and leave up to the arches only the needed
assembly which is now in arch_futex_atomic_op_inuser.

This effectively distributes the Will Deacon's arm64 fix for undefined
behaviour reported by UBSAN to all architectures. The fix was done in
commit 5f16a046 (arm64: futex: Fix undefined behaviour with
FUTEX_OP_OPARG_SHIFT usage). Look there for an example dump.

And as suggested by Thomas, check for negative oparg too, because it was
also reported to cause undefined behaviour report.

Note that s390 removed access_ok check in d12a2970 ("s390/uaccess:
remove pointless access_ok() checks") as access_ok there returns true.
We introduce it back to the helper for the sake of simplicity (it gets
optimized away anyway).

      arm64: dts: marvell: add Device Tree files for Armada-8KP · bf32f2ae
      由 Hanna Hawa 提交于 
      This commit adds the base Device Tree files for the Armada 8KPlus.
The Armada 8KP SoCs include several hardware blocks, and this
commit only adds support for the AP810 block, that contains the CPU
core and basic peripherals.

AP810 is a high-performance die, includes octal core application
processor based ARMv8-A architecture, two standard high speed DDR4
interface, and GIC-600 interrupt controller.
AP810 Built as part of Marvell’s MoChi AP family products.

Armada-8080 (8KPlus family), include an AP810 block that contains
the CPU core and basic peripherals.

This commit creates the following hierarchy:
 * armada-ap810-ap0.dtsi - definitions common to AP810
 	* armada-ap810-ap0-octa-core.dtsi - description of the octa cores
		* armada-8080.dtsi - description of the 8080 SoC
			* armada-8080-db.dts - description of the 8080 board
